Chemical Structure

4-Methoxybenzaldehyde-α-d1 CAS 19486-71-6 chemical structure

Description

As a certified reference material (CRM), 4-Methoxybenzaldehyde-α-d1 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

4-Methoxybenzaldehyde-α-d1 (CAS 19486-71-6) is a high-purity analytical reference standard with the molecular formula C8H7DO2 and a molecular weight of 137.15 g/mol.

Structurally, 4-Methoxybenzaldehyde-α-d1 (C8H7DO2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 137.15 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
